Reference of Voltages in Symmetrical Components

Reference of Voltages: In power systems, we must choose clear voltage references. We refer phase voltages to ground in grounded systems. Meanwhile, we refer positive and negative sequence voltages to neutral. Therefore, voltage‑to‑neutral and voltage‑to‑ground terms act interchangeably for positive and negative sequences. However, zero sequence requires careful distinction. Thus, proper referencing ensures accurate fault analysis. Phase and Sequence Voltage...
